Hello
Short time lurker , first time poster.
Just asking a question here as I live down under in Australia, finding parts online is a bit difficult. What I could find in our version of 'home depot' was all galvanised pipe. Most shops that sell this stuff are trade only stores that don't want to bother selling 1 or 2 pieces to the public. Plus getting to the stores is impossible as they are only open Mon-Fridays and shut weekends.
I found this which looks the goods for the reducing tee.
1"x 3/4" black iron plumbing T

However all I could find for ¾" x 6" black iron nipple was impossible to find online they were all too short.
Could I use a the following 316 Stainless extended barrel nipples instead of a black steel.
